I have a Gateway MX6426 Notebook. I recently bought a new battery and power cord for it.When I got the battery and installed it,the pc came on just fine for about 10 minutes then shut down.When I tried to reboot,I get 4 red blinking lights from front indicator.The pc doesnt try to boot up,no fan noises...nothing.Could the battery be defective?

Found out the issue.I tested the battery and power cord with meter...issue was with the power jack.I noticed while wiggling the power cord the laptop powered on.So I resolved the issue.Thank you for your help tho.
